CONCRETE FILING FOR BULKHEADS.

Specification of Letters Patent.

Patented Oct.. 3, 1911.

Application filed February 18, 1911. Serial No. 669,39'9fl an improved form of sheet piling of4 rein? forced concrete, so that it will be simple to drive, 'eilicient in use, and have closed joints.

A v particular obj ect isto so devise the piles that the adjacent piles may be attached or secured together near theirbase, so `that `there will be no tendency to spread out fan- Wise at the base, which heretofore has restilte/d in making necessary the use of wedge shaped special pieces to take up the differences in alinement. I am thus enabled to make the individual piles standard and uniform in all respects, and do away with special work on the job to a great extent. j

The'form of reinforced concrete piling which I prefer 4to use is one having what is known as shipnlap joints, and I prefer Vto drive them by a jet of water displacing the sand or earth at their base into which cavity the piles are sunk. My improved sheet piling, is particularly applicable for use 1n bulkhead work.

My preferred 4form of piling is properly reinforced, and of cast or molded concrete, so that one .surface shall be of greater breadth than the other surface, while the sides are formed with reversed steps, one Y step having a wider tread than `the other. As a consequence-there will be a space left between the meeting faces on one surface of the pile, while no s ace will be left at the other surface. lWit in the space so left on one surface of the pile near its base, lI rovide a hook on one pile, and a loop on hat side of the pile which is to be next to it, so that when a number ofpiles are in place the loop will engage the hook andV hold the piles snugly together in proper vertical alinement .at their base. I prefer that these hooks and loops for bulkhead work be a short distance above the solid bed.'

The piles are preferably each formed with a hole some distance from'thetop, forthe passage of a bolt, so that they may be bolted togetherbyL means of a. horizontal Stringer preferably also of reinforced concrete, while the tops of the piles are provided with a cap also of reinforced concrete, and preferably extending to one side of the sheet piling the same distance as the horizontal Stringer.

The cap is preferably formed of reinforced concrete, and may be made separate from the piles, and ut into place by grout or it may be molded) or cast in place.` I preferablyprovide it with openings at right angles to its length for the bolting of wooden fender piles thereto.

In order that the piles may nest snugly together at their base without spreading as they penetratethe sand or soil, Iprovide-a long tubular pipe, which I first place over a hook on a Apile already vertically driven, the

pipe passing through the loop on the pile y.

about to b'e driven so that the pile, even ifj started at a cant, will have its sharp lower edge resting tightly against the side of the already driven pile, and prevent sand, rocks and stone -from getting between the bottom edges of adjacent piles. The deeper the pile is driven the more will even a canted pile be brought into vertical position, although each individual pile should be driven vertical without the cant, the sharp edge in any' instance serving to plow j awayV any material that might otherwise lodge between adjacent piles. After the p ile is sunk to its proper depth the loop w1ll surround not-only the pipe but the hook of the previous pile, when the pipe Inay be withdrawn,\and used for the next drlvlng. In this way, all piles will hug each other closely at their base, where theyy are within the bed, and as that is the only pomt where there is any great difficulty of proper almevment, the piles may be driven each one in a a front elevation showing one pile, partly broken awa and a second pile in proper vposition to e in its sinking.. The slant of Fig. 47 is a front elevation of sheet piling built according to my invention, properly capped with a Stringer and fender pilein place. Fig. 8 is a-side elevation of Fig. 7. Fig. 9 is an enlarged front elevation of a section of the capping stone for the sheet piling. Fig. 10 1s a section through line 10'-10, Fig. v

As shown in the accompanylng drawlngs,

1 is one of the unit piles of the series which I use. I t is formed with an oblique lower edge 2, terminating in a point. Within the concrete, a short distance above what is to be the bed in which the piles are sunk, I provide lan iron formed with a loop 3, and a hook 4. Each pile is formed with a surface 5 of greater width than its opposite surface 6, and with two steps, one the step 7 having a tread narrower than the step 8. The hook 4 is located between the surface 6 and the tread of the step 8, while the ring or eye 3 is located as shown inFig. 4, at the left hand side between the tread 7 and the surface 6.

y Consequently when the piles are nested together as shown in Fig. 4, there will be a space 9 vleft between adjacent piles on one side, while they. will meet and join each other on their other surface. The purpose of the hook and eye is to hold together at their base adjacent piles to prevent their opening out fanwise, and necessitating as a consequence V shaped adjusting piles. Where the material of the bed will permit the piles may. be vertically sunk, one after the other, and the hooks caused to engage with the irons, but as there is a tendency to spread at the base, I prefer to extend the hooks so that the hook will have a greater distance to enga 'e the'eye ofthe adjacent pile. This would o viously use considerable metal which is Y likely to bend, if the extension of the hook were integral therewith, and of its diameter, and hence I substitute for the extension of the hook a temporary extension in the shape of a tubular pipe 10, which may be passed over the hook and through the eye of adj acent piles, and then the pile lowered along the pipe either vertically or at the slight cant at the beginning of the operation until the pile begins to penetrate the bed. When the pile is penetrating the bed, the pile being sunk should` bein vertical position, and slide down the pipe until the, hook is engaged b the ring, when the pipe 10 may be remove This pipe, hook and ring Yhelp to A keep the plow edge of thesinking pile close up to the preceding one, and keep all dirt f yint'orcinf.; caps may be cast, and put in position in sections, their joints ,with the to`p of the piling being well grouted or a frame may be put in position and the caps cast in place as is quite common in concrete work.

I claim as -my` invention:

' 1. Sheet piling of the'class described, consisting of a series of similar concrete piles, a hook near the base of one pile, a loop to engage the hook on the adjacent surface of the next pile, means for guiding an unsunk pile, so thatl the hook and loop will keep in line and permit the foot of the ile being sunkto rest closely against the si e of the already sunken pile. v f' 2. Sheet piling of the class described, consisting of a series of similar concrete piles,

each pile havingl offset portions on opposite endsof opposite sides of each pile, an offset portion at on'e side being longer than that at the opposite side, so that when the parts are assembled a space is left between certain portions of adjacent piles, the space thus formed between adjacent piles having rcspectively a hook and an eye near their base, occu ying the space between these surfaces of a jacent piles which do not meet.

3. The herein described sheet piling consisting of a number of piles, eachhaving oli'- set portions on opposite ends of opposite sides of each pile, an odset portion at one side being longer than at the opposite side, so that when the parts are assembled a space is left. between certain portions of adjacent and an eye inline therewith on the other pile, and means for guiding the eye on the hook during the insertion of one pile into place adjoining a sunken pile.
